Note that you're not guaranteed to get the correct Muppet even if you use the proper formula. In particular, the ones that take twelve hours to obtain (6 through Harv-E and another 6 in the Digitizer) may take several attempts before they work right.(You'll know you got the WRONG muppet if the time listed is shorter than what should have appeared.)

Below is a quick Digitization Guide to Stage Two (The Kitchen). Some of the formulas are different because not all the same Muppets are available on this stage!

Food costs to "level up" are the same, but it takes longer to Digitize Muppets in this location
(the starting Muppets like Animal all take two hours per step, and Big Mo (at least I THINK that's
who I'm digitizing right now!) takes six hours per step.

It's also more expensive to instantly buy a Muppet with Gems (something I recommend you NEVER do), ranging from 150 to 500 Gems per Muppet.

The Dressing Room upgrade costs are also more expensive and take longer. (I think it's 15,000 Coins and 8 Hours for the FIRST upgrade, so the last one will probably be a small fortune.) Since you're limited to 4 Rooms in the first dressing room, you'll probably want to start the first dressing room upgrade ASAP.
